Description

[Detailed explanation of the invention] <Industrial application field> This invention lowers windows, balconies, etc. grids and handrails built into square outer frames as necessary, and is useful for evacuation in emergencies and large furniture. This invention relates to a support device for gratings and handrails that does not obstruct carrying into and out of a room.

<Prior art> A support device for supporting a handrail frame outside the outer wall of a building so that the handrail frame can be lowered in an emergency is known from Japanese Utility Model Application Publication No. 48-98918. Vertical guide rods are installed between the upper and lower brackets installed in pairs on the left and right sides of the exterior wall, and connecting fittings guided by the guide rods are installed on each vertical stile on the left and right sides of the handrail frame. The stile is received by the supports attached to the outer wall of the building with a gap maintained between the left and right lower brackets.

<Problems to be solved by the invention> In this way, guide rods are provided between the upper and lower brackets on the left and right sides, and connecting fittings that slide along the guide rods are attached to the left and right vertical frames of the handrail frame, and The structure is complicated, as it is also necessary to provide a catch for the lower stile to rest on.

To lower the handrail frame, lift the entire frame slightly and release the lower stile above the catch.
Tilt the entire frame and lower it so that the lower stile is in front of the tip of the catch, and let the upper stile catch the catch.

Therefore, it takes a lot of force to lift and tilt the entire frame, and in order to be able to tilt the handrail frame with respect to the guide rod in this way, the connecting fittings are rotatably connected to the left and right vertical frames. This makes the structure more complicated, and the guide rods of the upper and lower brackets spoil the appearance.

<Means for solving the problem> Therefore, the present invention is designed to make the left and right stiles of windows, balconies, etc. built into square outer frames, lattices, and handrails protrude outward from the outer wall of the building using upper and lower brackets, respectively. In a support device for a lattice or handrail, each of the left and right upper brackets is provided with a sliding contact protrusion that protrudes opposite to each other and slides into sliding contact with the left and right vertical stiles in the vertical direction, and each of the left and right vertical stiles A series of removable pins are passed through the upper part and the sliding protrusion in the front-rear direction; each of the left and right lower brackets has a cylindrical part at the tip that allows each of the left and right vertical frames to pass through in a vertically slidable manner. It is characterized by having been provided.

<Operation> A series of pins pass through the sliding protrusions of each left and right upper bracket and each left and right stile to maintain the lattice and handrail in an elevated position. To lower the lattice or handrail, remove the pin. As a result, the left and right stiles are guided by the cylindrical portion at the tip of the lower bracket to descend, and the upper stile comes into contact with the upper surface of the cylindrical portion of the lower bracket, stopping the descent.

<Example> In each of the illustrated examples, 1 is the square outer frame of the lattice or handrail, a is the left and right vertical stile, b is the upper stile, and c is the square outer frame of the grid or handrail.
is the lower stile, 2 is the left and right upper brackets, 3 is the sliding contact protrusion, 4 is the pin, 5 is the left and right lower brackets, 6
indicates the cylindrical portion at the tip.

In the embodiment shown in FIGS. 1 and 2, a groove 7 that is open at the upper end is provided at the upper part of the outer peripheral piece of the left and right vertical stile a, and the upper stile b
At each end of the upper surface, there is a notch 8 that communicates with the groove 7.
will be established. A block that fits into the space formed by the groove 7 and the notch 8 is used as a sliding protrusion, and this is fixed to the opposing surfaces of the left and right upper brackets 2 with bolts 9. This block or sliding contact protrusion 3 has a through hole 10 in the front and back direction for passing the pin 4, so the pin 4 can be passed through the front side of each left and right vertical frame a, the through hole 10, and the rear surface of the vertical frame in the front and rear direction. The pins 4 fix the upper parts of the left and right stiles a to the upper bracket 2, and keep the outer frame of the lattice and handrail in an elevated state.

The lower bracket 5 has a cylindrical portion 6 whose inner shape matches the cross-sectional shape of the vertical stile a, and the vertical stile a is connected to the cylindrical portion 6.
It is held so that it can slide vertically.

In addition, 3' indicates a flange which extends from both side edges of the block and, if necessary, from the lower edge, and contacts the outer surface of the edge of the groove 7 of the stile a.

Therefore, by removing the pin 4 as necessary, the outer frame guides the vertical stile a to the cylindrical part 9 of the lower bracket, and descends until the lower surface of the upper stile b is received by the cylindrical part 9 (dashed line in Figure 1). .

In this embodiment, when the grid or handrail is used to prevent falls, its weight is on the pin 4, so the pin cannot be easily pulled out by a child's prank, etc. If necessary, a hole 4' may be provided at the tip of the pin, into which a split pin or the like may be inserted. Furthermore, a pin 5a passing through the vertical stile a is passed through the cylindrical portion 6 of the lower bracket,
In addition to removing pin 4 of the upper bracket, remove this pin 5.
It may be possible to make it impossible to descend unless a is also removed.
Further, in this embodiment, the upper bracket 2 and the sliding contact protrusion 3, which is a block, are molded separately, but they may be integrally manufactured from aluminum casting or the like.

The embodiment shown in FIG. 3 differs from the above-described embodiment in that the upper bracket 2 has two contact pieces as sliding contact protrusions 3 that contact the front and rear surfaces of each of the left and right vertical frames a. A hole 11 for passing the pin 4 is provided in the contact piece. Therefore, the upper bracket 2 is formed in an F-shape with both contact pieces.

In this embodiment, the base end of the upper bracket 2 is hinged to a mounting piece 12 attached to the outer wall of the building, and the sliding protrusion 3 contacts the front and rear surfaces of the vertical stile a. an inwardly rotating state of
It is made to be able to rotate outward as shown by the arrow to an outward rotating state where it moves away from the vertical stile a. Incidentally, inward rotation beyond the inward rotation state is prevented by, for example, a stopper piece 13 integrally provided at the base end of the upper bracket colliding with the mounting piece 12.

Therefore, the upper bracket is rotated inwardly, and in this state, pins 4 are passed through the sliding protrusion 3 and the upper part of each vertical stile in the front-rear direction, thereby supporting the outer frame so that it cannot be lowered. When necessary, the outer frame can be lowered until the upper stile b is received by the cylindrical portion 6 of the lower bracket, as in the previous embodiment, by removing the pin 4. Of course, in addition to removing the pin 4, the outer frame can be lowered more quickly by rotating the upper bracket outward.

<Effects of the invention> According to the invention, by pulling out a series of pins that pass through the sliding protrusion provided opposite to the left and right upper brackets and the upper part of each left and right vertical stile, the left and right lower parts can be removed. The outer frame of the lattice or handrail can be lowered until the bottom surface of the upper stile is received by the cylinder part of the bracket that slides through each stile. It does not require any force and has the excellent effect of providing an appearance that is no different from a non-descending grid or handrail.
